| 摘 要： | 选用11种概率分布函数，分析了鄱阳湖流域“五河”6个水文站年最小连续7EI平均流量（或称极值流量）。概率分布函数的参数以及拟合优度分别由线性矩与柯尔莫哥洛夫一斯米尔诺夫方法（K—S法）检验，选出最适合该区极值流量分布函数，同时运用Mann Kendall（M-K）方法对极值流量趋势进行分析，对引起该流域水文极值变化的原...

| Abstract: | In this study,11 probability distribution functions are adopted to systematically analyze the probability behaviors of the 7-day low flow regimes(the minimum average flow for the consecutive 7 days) at six hydrological stations located in the Five Rivers in the Poyang Lake Basin.The L-moment technique is used to estimate the parameters of the probability functions and the Kolmogorov-Smirnov method(K-S) is accepted to evaluate the goodness-of-fit of the probability functions.Trends within the 7-day low flow ... |
